Publish distributions to TestPyPI on each day

[HideakiImamura]

Depends on #2238.

Motivation

Currently, we publish distributions to PyPI and TestPyPI at the same time when the release, so we cannot detect any error on publishing to PyPI beforehand. This PR proposes to publish to TestPyPI on each master push. It is a room of discussion for the trigger of the publish.

I have changed the uploads to be done every weekday. See #2220 (comment).

@not522 Could you review this PR if you have time?

@hvy Please feel free to add comments if you have any.

Thank you for your PR. More frequent upload to TestPyPI will prevent configuration error like this one.

I wonder if we can upload the packages with the same names multiple times. I think the duplicated package was refuled by PyPI.

You are right. From here, we cannot re-upload the same version to PyPI and it is the same for TestPyPI from here. I think we have to create a different branch changing the version dependent on the commit hash (if the trigger is the master push).

[HideakiImamura]

@toshihikoyanase The upload on each master push seems to be impossible since the version name should be different for each upload and the version name cannot include the commit hash according to PEP440.

I have changed the trigger to upload TestPyPI each weekday. PTAL.

[HideakiImamura]

I confirmed the TestPyPI upload succeeded not by the scheduled event but by the push event. See here
